To provide a vehicle body side part structure and manufacturing method therefor, capable of significantly suppressing electrolytic corrosion of a side sill.SOLUTION: A vehicle body side part structure includes a side sill outer 27, a side sill stiffener 26 and a first cutoff member 16. The side sill outer includes a steel first outer part 45 and an aluminum alloy plate second outer part 46. The side sill stiffener is a steel member and includes a first opening part 35 formed, spacing from a joined part 48 formed by joining the first outer part and the second outer part. The first opening part 35 is opened to connect a first closed cross section 21 with a second closed cross section. The first cutoff member is arranged between the first opening part and the joined part and inside the second closed cross section.SELECTED DRAWING: Figure 3

    【課題】サイドシルの電食を良好に抑制できる車体側部構造及び車体側部構造の製造方法を提供する。【解決手段】車体側部構造は、サイドシルアウタ27と、サイドシルスチフナ26と、第1止水部材16と、を備える。サイドシルアウタは、鋼製の第1アウタ部45と、アルミニウム合金板製の第2アウタ部46と、を備える。サイドシルスチフナは、鋼製の部材であり、第1アウタ部および第2アウタ部が接合された接合部48に対して、間隔をおいて形成された第1開口部35を有する。第1開口部35は、第1閉断面21と第2閉断面とを連通するように開口されている。第1止水部材は、第1開口部と接合部との間で、かつ、第2閉断面の内部に配置されている。【選択図】図3
